商店页面和产品页面上的Woocommerce库存状态

Question

美好的一天，

我正在使用此代码，但是库存状态仍为“有货”和“缺货”，还必须为“预购”和“根据要求”。

它发生在Wordpress Jupiter主题更新之后，大约几天后才寻找原因和解决方案。你能帮忙吗？

/* add custom stock status */
function woocommerce_add_custom_stock_status() {
    ?>
    <script type="text/javascript">
    jQuery(function(){
        jQuery('._stock_status_field').not('.custom-stock-status').remove();
    });
    </script>
    <?php   
    /* update custom status if backorder if varations updated */
    $real_stock_status = get_post_meta($_REQUEST['post'], '_stock_status', true );
    if($real_stock_status=="onpreorder") {
        $stock_status = get_post_meta($_REQUEST['post'], '_custom_stock_status', true ); //get status from custom meta
        update_post_meta($_REQUEST['post'], '_stock_status', wc_clean( $stock_status ));
    }

    woocommerce_wp_select( array( 'id' => '_stock_status', 'wrapper_class' => 'custom-stock-status', 'hide_if_variable custom-stock-status', 'label' => __( 'Stock status', 'woocommerce' ), 'options' => array(

}
